Substitute Part Grouping Explanation

Substitute parts are selected strictly on the basis of identical or better electrical and mechanical parameters. The allowed parameters for substitution are: Schottky technology, maximum DC reverse voltage of 90 V, average rectified current at or above 700mA, forward voltage at comparable current, fast recovery speed, reverse leakage current at 90 V, through-hole axial mounting, and compliance status. Only parts matching all these criteria within the specified product category of diodes and rectifiers are included.

Engineering Selection Recommendations

The Sanken Electric USA Inc. AK 09 diode is obsolete. Substitute selection is based only on matching product status, compliance certifications, and provided environmental designations such as RoHS compliance and MSL. Both the AK 09 and the SB190-T are RoHS compliant and have Moisture Sensitivity Level 1 (Unlimited). The SB190-T is active and thus suitable as a substitute strictly within regulatory and compliance bounds.

Frequently Asked Questions (FAQ)

Q: What are the essential criteria for selecting a substitute for the AK 09 diode?
A: Substitutes must match Schottky technology, 90 V DC reverse voltage, average rectified current at or above 700mA, axial through-hole mounting, compatible package, and compliance status.

Q: Is the package type significant in substitution?
A: Yes. Substitution is based on matching through-hole axial packages to ensure mechanical compatibility.

Q: Can the forward voltage and reverse leakage differ between the AK 09 and substitutes?
A: Substitute selection is limited to parts with similar or improved forward voltage at comparable current and reverse leakage characteristics at 90 V.

Q: Are compliance and certifications considered in substitute selection?
A: Only RoHS status and Moisture Sensitivity Level (MSL) provided in the parameters are considered.

Q: Does operating temperature affect the selection?
A: Operating temperature ranges are allowed as provided; the substitute SB190-T supports a compatible range as specified.

Q: Are alternative mounting types permitted for substitution?
A: Only through-hole axial mounting, as per the provided parameters, is accepted for substitution.
